This study investigates the fabrication of biodegradable water-absorbent materials using pineapple stem starch (PS) in combination with plasticizers and agricultural fiber waste. Glycerol and polyethylene glycol were applied as plasticizers to enhance flexibility and water uptake. Agricultural fibers - namely hemp core, pineapple leaf non-fibrous material (NFM), and whole grain leaf (WGL) - were blended with PS and additives (carboxymethyl cellulose and sodium alginate) and processed via twin-screw extrusion. The resultant composites exhibited water absorption capacities ranging from 100% to 400% after 5-24 hours of immersion. WGL-based materials showed superior water uptake compared to hemp and NFM. The addition of 5 wt% CMC and SA marginally improved water absorption and pellet cohesion. These biodegradable composites show promise as eco-friendly alternatives for use in domestic cat litter applications.
